These are definitely pretty OK photos. The first one has pretty shallow depth of field for this photograph, which we've seen a lot of. The shallow DoF might make it a little different? I'm not sure how I feel about it. You've cut off the crown a bit on the edges, though, it needs more horizontal room.
The second one isn't anything much. You had an idea, and that's good, but the result isn't worth anything. The star trails are nice, and the aircraft cutting across them is a nice touch, but the bonfire is rendered as a smudge and all the stuff on the ground is just a clutter of unappealing stuff. Can you imagine printing this and putting it on your wall? Would you use it as a background on the computer screen? I'm sure you LIKE it, but can you imagine a use for it that you'd actually like?
The third is a perfectly nice picture of a bug. It's slightly soft, but whatever. It's a bug picture, and a pretty decent one. Bug pictures do zip for me, but lots of people like them. Unfortunately for you, most of those people like razor sharp bugs. It's kind of a thing, taking fuzzy pictures of tiny things is pretty easy, so there's a premium placed on SHARP.
The last one is quite lovely. I really like the linear ripple on the water in the middle of the frame, it's a lovely touch. On the down side, when you make it bigger you notice that there are wires strung over the water and a bunch of radio? electrical? towers on the background horizon. It's also a bit soft, but soft can be OK in landscapes. It's a soft and moody scene, so I think soft works ok here.
What I am not seeing here is any kind of vision. What I am seeing is decent but not brilliant copies of photographs we've seen quite a lot of. Done with a touch more artistic flair and better technique, these would be candidates for flickr's explore -- whatever you make of that particular accolade. Opinions vary, to put it mildly.
There's nothing wrong with trying to emulate photos you like, it's a great exercise and it's perfectly reasonable that simply doing that would satisfy you fully. No problem. You can up your game by making these things sharper and punchier, and you can up your game by being more picky about things like cropping, wires across the lake, and so on. This will get you up to "flickr explore" level, which is a pretty high standard for a certain kind of photography.
If emulating photographs that have been made before many times is NOT going to float your boat forever, you're going to have to ALSO work at creative ideas and making something more distinctly your own.
